Abstract

Automatic coin telephone station and central office systems have advanced recently to the point where facilities have been designed for accumulating at a centralized location data on the exact numbers and types of coins deposited in coin phones. This disclosure presents an arrangement for automatically processing a coin box removal signal (88) from a coin telephone station (1) to the central office (6) so that a determination can be made of the exact numbers and types of coins in the coin box at the time of its removal from the coin phone for collection. Each station is equipped with memories (16, 17, 18) for three different types of coins and a coin box removal memory (83). Flip-flop and logic gating control circuitry (26) is responsive to interrogate and coin collect signals received from a central office for sequentially interrogating the memories and frequency shift keying the stored information to the central office. Coin processor and memory circuitry (60) in the central office interrogate the memories (16, 17, 18, 83) for initial and overtime deposits and coin box removal data and then store and accumulate the actual coin denominations for correlation in connection with coin box fill determinations and collection scheduling as well as the ascertaining of the exact numbers and types of coins in the coin box at the time of its removal from the phone.
